Sensing Solutions

The CurrentWatch EACR Series current sensor family from Eaton’s electrical business combines a current sensor and a “True RMS” signal conditioner into a single package. The EACR Series provides True RMS output on distorted waveforms found on VFD or SCR outputs, and on linear loads in “noisy” power environments. Available in solid- or split-core housings.

For typical applications of the CurrentWatch EACR Series, see listing below.

Product Features

• True RMS Output — True RMS technology is accurate on distorted waveforms like VFD or SCR outputs
• Jumper-Selectable Ranges — Reduces inventory and eliminates zero and span
• Isolation — Output is magnetically isolated from the input for safety and elimination of insertion loss (voltage drop)
• UL, C-UL and CE Approved — Accepted worldwide

Typical Applications

• VFD Controlled Loads — Monitoring VFD output indicates how the motor and attached load are operating
• SCR Controlled Loads — Accurate measurement of phase angle fired or burst fired (time proportioned) SCRs, with faster current measurement than temperature sensors
• Switching Power Supplies and Electronic Ballasts — True RMS sensing is the most accurate way to measure power supply or ballast input power
